In this study, a medicinal herbal plant, Meliae fructus, was examined and screened for anti-Helicobacter (H.) pylori activity. Seventy percent ethanol was used for herbal extraction. For anti-H. pylori activity screening, inhibitory zone tests as an in vitro assay and in vivo study using a Mongolian gerbil (Meriones unguiculatus) model were performed. Also, the safety of herbal compounds was evaluated by animal study. As a result of inhibitory zone test, Meliae fructus extract demonstrated strong anti-H. pylori activities. Also, as results of in vivo animal studies, Meliae fructus demonstrated strong therapeutic effects against H. pylori infection according to the criteria of histological examination and rapid urease test. As results of the safety study, after 28 days treatment of the Meliae fructus extract, the animals were not detected any grossly and histological changes. These results demonstrate that it can be successfully cured against H. pylori infection and protected from H. pylori-induced pathology with Meliae fructus. It could be a promising native herbal treatment for patients with gastric complaints including gastric ulcer caused by H. pylori.
